' REVERSIBLE SLIP SHEETER Filed Nov. 5. 1928 M Inventor Attorney Patented Oct. 22, 1929 UNITED STATES PATENT OFFICE REVERSIBLE SLIP SHEETER Application filed. November 1928.

My invention relates to improvements in reversible slip sheeter and it more especially consists of the features pointed out in the annexed claims.

5 The purpose of my invention is to prov de a slip sheeting device which utilizes a palr of rolls that receive a web of porous material. such as paper, etc.; that as the web is wound on one roll printed sheets are at the same time wound in it, as the web is unwound from the second roll; that simultaneous with the windinn up of freshly printed sheets onto the first roll previously printed and blotted sheets are delivered from the second roll; that utilizes an idler roller near the duplicator over which the web passes in traversing from one roll to the other; that provides a horizontal delivery table associated with the idler roller wherebV both may be swung on a horizontal plane as a unit so as to be moved away from within the fold of the web; that supports the two paper rolls in a single frame forminga reel rotatable approximately on a horizontal axis in a second frame so that the two rolls may be transposed in position, the one for the other; that makes provision for rotating the second frame approximately on a vertical axis so as to form a turntable for the rolls. thus presenting the opposite roll faces to the duplicator; that releasably holds the several frames in a fixed relation to a main supporting; frame; and that by reason of the several cooperating parts makes it possible'to simultaneously load one roll while the other roll is being unloaded.

With these and other ends in view. I illustrate in the accompanying drawing such instances of adaptation as will disclose the broad underlying features of my invention without limiting myself to the specific details shown thereon and described herein.

F ig. 2 is a front elevation of Fig. 1, showing the web omitted from between the rolls.

Fig. 6 is a diagrammatic View showing the rolls of Fig. 5 reversed.

In practically carrying out my invention I may use whatever alternatives of construction that the exigencies of varying conditions may demand without departing from the broad spirit of my invention.

In the main the structure simply comprises a vertical frame joined to a horizontal frame which positions the device in tandem with any desired form of duplicator. The main frame comprises two vertical standards 25 joined at the top by a cross member 24 and at the bottom by a cross member 26. The horizontal frame is formed with two members 17 each one being attached to a vertical member 25 and at their outer end adjacent the duplicator they are joined by a cross member 19.

At the bottom end of the vertical members 25 castings 37 may be attached. These castings hold adjustable legs 38 by means of which the vertical position of the frame 17 may be adjusted to the height of the duplicator table 36. Near the outer ends of the members 17 angle brackets 20 may be placed by means of which or otherwise the device may be held in fixed relation to the duplicator.

On the frame 17 an idler roller 10 and a receiving table 15 are positioned. Both may be swung horizontally as a unit on pivot 12 supported on a bracket 13. The pivot 12 has an extension 11, as shown in Fig. 3. which extends transversely of the frame 17 This extension has upwardly projecting bearings 43 for the idler roller 10 and two upwardly proj ecting brackets 14 for supporting the receiving table 15. This table may have sides 44 if desired.

The extension 11 has a downwardly extending projection 41 which abuts the cross member 19 and thus serves as a stop and the extension is held in place, as shown in Fig. 3, by a pin 42 or otherwise. The idler roller 10 and the receiving table 15 are swung horizontally on the pivot 12, as shown by the dotted curved lines on Fig. 3, so as to leave the web 9 free to be pulled taut between the two rolls, as shown in Fig. 4, when the lower roll is unloaded frame 28 may be calledthereel,- and 'the frame 30 with its end members 3l may be des-' ignated the turn table.
